Does anyone have suggestions for effective shapes and colors for compost and trash openings to discourage contamination in a student dining hall?

There is ample room for signs and displays depicting proper sorting, but we are wondering if certain shapes and colors have been shown to be more effective for helping people choose the right bin with minimal effort.

Any suggestions would be most helpful, thanks.
